In a geometry class, students are asked to describe the dimensions of a plane based on the components that create a plane. Which student’s response is correct? Mark states that a plane has zero dimensions because it is made up of three noncollinear points. Stacy states that a plane has two dimensions because it is made up of an infinite number of lines. Dewayne states that a plane has one dimension because it contains the line intersecting two points. Candice states that a plane can have multiple dimensions depending on how many points are labeled.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
